Definitions
- the invention relates to a cartridge with a cartridge case and a projectile according to the Features of the preamble of claim 1 and claim 9.
- the object of the invention is a cartridge according to the preamble of claim 1 and the preamble of claim 9 to improve in such a way that an unintentional burning of the cartridge avoided in the case becomes.
- the invention is based on the idea that an occurring In the case of the cartridge, the propellant lighter is prevented from propellant powder particles or can push parts of the propellant charge into the tracer set.
- the protective body is a filler that is between the breech and the tracer at the tail end is firmly arranged.
- the filler fills the space between the tracer set and the upper one Closure of the propellant lighter, so that between the tracer and no more propellant powder grains in the top cap of the propellant lighter can be located.
- the upper closure is designed such that its diameter is larger than the diameter of the rear end face of an interior of a tail unit and the Distance between the upper breech and the tail unit is so minimal that the propellant powder located between the shutter and the tracer charge the only slight axial movement possibility of the closure is not the tracer can ignite.
- 1 denotes a cartridge, which consists essentially of a cartridge case 2 and a sub-caliber arrow projectile 3 with sabot 15.
- the cartridge case 2 is composed of a sleeve jacket 16 made of combustible material and a sleeve base 7 made of metal.
- a sleeve jacket 16 made of combustible material
- a sleeve base 7 made of metal.
- the tube filled with igniter itself axially into the interior 17 of the cartridge case 2 filled with propellant powder 6 extends.
- Figure 2 is between an upper, preferably as a screw cap trained closure 9 of the propellant charge lighter 8 and the tracer 5
- Filler 10 made of inert material.
- This inert material can Plastic, for example made of hard foam or styrofoam or also from one material with at least 60% kraft pulp. Due to the inert material, a Self-ignition of the filler excluded.
- the filling piece saves weight Hollow body formed, the early in the functional firing by the Pressure build-up is destroyed and clears the way to ignite the tracer set.
- the filler 10 arranged at the rear end 11 of the rear end 4 is dimensioned such that the maximum diameter d 1 located at the rear is larger than the diameter d 2 of the tracer set 5.
- the filler completely fills the interior of the tail unit 14 and is firmly positioned within the tail unit and easy to assemble.
- the diameter d 3 of the closure 9 is greater than the diameter d 2 of the tracer set 5 and smaller than the diameter d 1 of the filler, so that the propellant charge lighter 8 is stopped by the closure 9 before the tracer set 5 is reached in the tail area.
- the tip 13 of the closure 9 is suitably dimensioned in the height h 1 smaller than the height h 2 of the filler.
- the diameter d 3 of the upper closure 9 of the propellant charge lighter 8 is larger than the diameter d 4 of the interior 14 of the tail unit.
- the closure 9 of the propellant lighter 8 is made of a material that Tail contact does not cause spark formation Proven use of brass fasteners on steel tail units 18.
